Agate Union Road
I was just a teenager (approx 1960/61) when the Union Road Agate first strike happened. My buddy Ron Scott and I rode our bicycles down the brand new interstate 55 yet to be opened. We checked out the new formed bluffs after the workers completed their blasting. Other St. Louis Mineral & Gem Society members were also checking the area. The first of the agate nodules found were at the Union Road exit on the east side of the new interstate. But, the vast majority was actually found a couple miles south on 55 at the South Lindbergh exit on the east side of the interstate. The area was deep in the Missouri red clay. To make things worse, there was plenty of rain. We searched other blasted bluffs all along the interstate, but we had no luck. One of my scout masters (Linus Hoffmeister) had hundreds of the Union Road nodules.
We have now sold all of the union road agates. if you have some you would like to sell, please contact me.
Yes! A pair set of the Old Union Road agate. I was in on this strike which was located in south st. louis county while they were building the new interstate 55. As a kid, we followed the workers after blasting the rock. The first agates were first found at the union road exit off 55 which is north of south Lindbergh exit. Now that was where about 98% of the agates were found. We walked in thick wet red Missouri clay. Was hard to get around and that area was only open for a short time. Yes! I am that old! Lol This pair weighs in at 7.3 Ounces. I actually purchased this from one of my consignee’s, but it is time to pass it on including the true history of the deposit.
